I made a C++ client app, which seems to work well. It's sending/receiving bytes just fine. The problem I'm having is requesting web pages from servers. I don't know how to retrieve files from sub domains (I think that's what they are lol).

Say I have the IP of a server: 70.84.66.196 (Cameron's server) -- I have a char array with a HTTP GET request:

char sendbuf[57] = "GET /index.php\nHost: www.techhelpforum.com\n";

What I'm getting is the "Three Poor Guys" index, not THF. See what I'm getting at?

I think the problem is my escape sequences. Any Ideas how make this work? I need the GET request to be all in one string too, btw.

Thanks,
Cache.

I am still 1/3 owner of it.

Without seeing the full code, I can't tell you why it isn't working. But what you posted should work from a glance.

Here is the full client code:

Code:

#include <winsock2.h>
#include <iostream>
#include <fstream>

using namespace std;

// Client

int main() {

    WSADATA wsaData;
    int iResult = WSAStartup( MAKEWORD(2,2), &wsaData );
    if ( iResult != NO_ERROR ) { cout << "Error at WSAStartup()\n"; }

    SOCKET m_socket;
    m_socket = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP );

    if ( m_socket == INVALID_SOCKET ) 
    {
        cout << "Error at socket(): " << WSAGetLastError();
        WSACleanup();
        system ("PAUSE");
        return 0;
    }

    sockaddr_in clientService;

    clientService.sin_family = AF_INET;
    clientService.sin_addr.s_addr = inet_addr( "70.84.66.196" );
    clientService.sin_port = htons( 80 );

    if ( connect( m_socket, (SOCKADDR*) &clientService, 
                  sizeof(clientService) ) == SOCKET_ERROR) 
    {
        cout << "Failed to connect.\n";
        WSACleanup();
        system("PAUSE");
        return 0;
    }

    int bytesSent;
    int bytesRecv = SOCKET_ERROR;
    char sendbuf[100] = "GET /somethinghere\n";   // <--What GET request?
    char recvbuf[10000] = "";

    bytesSent = send( m_socket, sendbuf, strlen(sendbuf), 0 );
    cout << "Bytes Sent: " << bytesSent << endl;

    
    if (!bytesRecv == 0 || 
        (bytesRecv == SOCKET_ERROR && 
         WSAGetLastError()== WSAECONNRESET ))
    {
        bytesRecv = recv( m_socket, recvbuf, 10000, 0 );
        if ( bytesRecv == -1 ) { cout << "Connection Closed.\n"; }
        cout << "Bytes Recv: " << bytesRecv << endl;
        cout << "\n" << recvbuf << endl;
    }
    
    string File = recvbuf;
    ofstream outFile;
    
    outFile.open("index.php");
    outFile << File;
    outFile.close();
    
    system("PAUSE");
    return 0;
}

Keep in mind this client does actually work, it's just figuring out what GET request to use for getting pages from sub domains (or whatever they are) that's a problem.

EDIT: If you want to compile this you will need to link the lib file: WS2_32.Lib
It comes with the Platform SDK.

Sometime this week the SDK will finish installing ...

Hm. I can get it to send bytes, but it isn't receiving ... Anywho, try this:

Code:

#include <winsock2.h>
#include <iostream>
#include <fstream>

using namespace std;

// Client

int main()
{
 	WSADATA wsaData;

	int iResult = WSAStartup( MAKEWORD(2,2), &wsaData );

	if ( iResult != NO_ERROR )
	{
	   	 cout << "Error at WSAStartup()\n";
	}

	SOCKET m_socket;

	m_socket = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP );

	if ( m_socket == INVALID_SOCKET ) 
	{
	   cout << "Error at socket(): " << WSAGetLastError();
	   WSACleanup();
	   system ("PAUSE");
	   return 0;
	}

	sockaddr_in clientService;

    clientService.sin_family = AF_INET;
    clientService.sin_addr.s_addr = inet_addr( "70.84.66.196" );
    clientService.sin_port = htons( 80 );

    if ( connect( m_socket, (SOCKADDR*) &clientService, sizeof(clientService) ) == SOCKET_ERROR) 
    {
        cout << "Failed to connect.\n";
        WSACleanup();
        system("PAUSE");
        return 0;
    }

    int bytesSent;
    int bytesRecv = SOCKET_ERROR;
    char sendbuf[100] = "GET / HTTP/1.1\nHost: www.spsac.net\n";   // <--What GET request?
    char recvbuf[10000] = "";

    bytesSent = send( m_socket, sendbuf, strlen(sendbuf), 0 );
    cout << "Bytes Sent: " << bytesSent << endl;

    if (!bytesRecv == 0 || (bytesRecv == SOCKET_ERROR && WSAGetLastError()== WSAECONNRESET ))
    {
        bytesRecv = recv( m_socket, recvbuf, 10000, 0 );
        
		if ( bytesRecv == -1 ) 
		{
		   	 cout << "Connection Closed.\n";
		}
        
		cout << "Bytes Recv: " << bytesRecv << endl;
        cout << "\n" << recvbuf << endl;
    }
    
    string File = recvbuf;
    ofstream outFile;
    
    outFile.open("index.php");
    outFile << File;
    outFile.close();
    
    system("PAUSE");
    return 0;
}

It will receive bytes if you remove the 'HTTP/1.1' from your GET request. But again this only gets the "Three Poor Guys" index. I'm pretty sure that's because anything after the first '\n' is being ignored.

Just an update. If I can't get this to work any time soon, I'll look into the Platform SDK WinINet API functions. That seems somewhat overly complicated for such a simple task, though.:roll:

http://msdn.microsoft.com/library/de...net/portal.asp

I've finally figured it out::

char sendbuf[] = "GET http://www.techhelpforum.com/index.php\n";


I can't believe that wasn't one of the first things I tried lol. I got this from the "Request" section of the HTTP/1.1 RFC 2616 -- which suggests you could be using some sort of proxy?. What's odd still, is that even the RFC specifies the request to a proxy should be:

GET http://www.techhelpforum.com/index.php HTTP/1.1

Note the HTTP part at the end. For some reason I never get a response if I pop the HTTP bit in the request string.

Glad you got it Cache! :thumbs:
